Short answer: Psalm 139:13–16 says the living God formed the psalmist's inmost being and knit him together in his mother's womb, and that this happened in secret where no human eye could see. God saw the unseen stages and recorded the days of that life before any of them existed. The passage gives no instruction about artificial intelligence; it gives a doctrine of the person. Whatever tools humans build, they remain creatures working on creatures, never the source of a person's worth and never the searcher of a heart.
Where the Psalm turns from everywhere to the womb
Psalm 139 is David's prayer, spoken directly to God in the first person from beginning to end. It is poetry and confession, not a technical account of anything. The psalm opens with a man who has been searched and known, whose thoughts God perceives from far off, and it moves through a series of locations where he cannot escape God's presence. Verses 13 through 16 sit at a hinge. The question of where a person can go has just been answered with nowhere, since darkness does not hide from God. Now the psalm turns from God's everywhere-presence to his intimate care in forming a life.
The literary shape matters for reading these verses rightly. Verses 7 through 12 press the question of flight and find no exit, because night shines like day to God. Then the psalmist stops running and remembers the womb. The God who fills every place was present at his beginning, forming his inmost being and knitting him together. Verses 17 and 18 follow with wonder at the vast sum of God's thoughts and the calm confidence that when he wakes he is still with God. The movement is from being known, to being unable to hide, to being made, to being held.
The covenant setting is Israel's faith in the Creator who made and sustains his people. That context keeps the passage from becoming a cold report about data. God's knowledge here is not surveillance but the attention of a maker to what he has made, and the psalmist answers it with thanks and awe rather than fear. Notice too what the text does not claim. It speaks of God's work and the speaker's trust, not of health, safety, or protection from harm, and it says nothing for or against any technology. It simply locates a human life inside the care of the God who was there at its beginning.
What the Psalm says about being formed and known
The psalmist moves from being known to being made. In 139:13 he says that God formed his inmost being and knit him together in his mother's womb. Both pictures suggest deliberate, skilled, personal work: a potter shaping, a craftsman weaving. Nothing here sounds like mass production or accident. The hidden season of gestation is not hidden from God. In 139:15 the frame made in secret and woven together is fully seen by the one doing the weaving. The psalmist is not describing a process he watched; he is confessing what God was doing when no human eye was watching.
Then comes the confession: "I will give thanks to you, for I am fearfully and wonderfully made. Your works are wonderful. My soul knows that very well." (Psalm 139:14). The phrase fearfully and wonderfully describes existence that evokes awe and reverence, not a claim about perfection or ease. Notice where the psalmist grounds it: in God's works being wonderful, not in his own achievement, appearance or usefulness. His worth rests on the maker's skill, not the product's performance. That is a wisdom confession of trust, not a promise that every body will be healthy or every life free from harm.
In 139:16 the psalmist says God's eyes saw his body and that all its days were written in God's book before any of them existed. The book is God's own record, and the days ordained were written when as yet there were none of them. That places the beginning of a human life inside God's prior intention, not inside human planning alone. The point is God's knowledge and care, not a slogan for or against any technology. Machines can copy, sort and generate, but they cannot be the one who knits, sees and writes. The psalmist's comfort is that he belongs to that maker.
The God who formed us in secret
Psalm 139 begins with a man who knows he has been searched. God has examined him, knows his thoughts from afar, and understands his words before he speaks them. Verses 7–12 then ask where anyone could flee from God's presence, and the answer is nowhere: darkness cannot cover a person, because night shines like day to him. Verses 13–16 take that everywhere-present God and show him close, at work in the hidden place of the womb. The knowledge described here is not cold data collection. It is the attention of a maker to what he has made, and the surrounding verses make that plain.
The central claim is stated directly: “For you formed my inmost being. You knit me together in my mother’s womb” (Psalm 139:13). God is credited with the inward life as well as the body, and the forming happened where no human eye was watching. Verse 15 says the psalmist's frame was not hidden from God when he was made in secret. Verse 16 adds that God's eyes saw his unformed body and that his days were written in God's book before any of them existed. The hidden, unimpressive stage of life is as much God's handiwork as the visible one.
This gives no instruction about machines. It gives a doctrine of the person against which every claim about machines must be measured. Whatever tools humans build, they are creatures working on creatures; they are never the source of a person's worth and never the searcher of a heart. Verses 17–18 respond with wonder at the vast sum of God's thoughts and the confidence that when he wakes he is still with God. The passage promises no health or safety. It does say that the God who made us in secret has been paying attention all along.
Where readers disagree about this Psalm and machines
Evangelical readers agree on the ground floor of this psalm: God is the maker of human life, and persons bear his image. They part ways on how far the psalm reaches into technology. Some read verses 13–16 as a strong word against treating people as data or products, since God forms the person and sees what no system sees. Others insist the text says nothing about tools and should not be stretched into a verdict on any device. The disagreement is real, and neither side should be caricatured.
Two further debates sit inside these verses and should not be smuggled into a discussion of machines. Verse 15 speaks of being made in secret, and verse 16 of days written in God's book before any existed. Readers differ over how directly these bear on the beginning of life and on how God's foreordained days relate to human choices. Those are weighty questions about persons, not about software. What stays central across the differences is that God alone searches the heart, forms the person, and owns the days.
The text also sets its own limit. It describes God's work and the psalmist's response; it issues no command about devices, and it promises no health, safety, or protection from harm. So it cannot be turned into a slogan for or against any particular technology. What it does say is that the darkness does not hide from God and the night shines as day to him, and that he formed the psalmist's inmost being. That is a word about the Maker and the made, and it leaves every tool in its place.
Formed in secret, known by God
David moves from the darkness he cannot escape to the womb he never remembers. In 139:13–16 he says that God formed his inmost being, knit him together, and saw his frame when it was made in secret. The language is personal and deliberate: not mass production but craftsmanship. God's eyes saw the psalmist's unformed body, and his days were written in God's book before any of them existed. Notice what the passage claims and what it does not. It says human life belongs to God from its hidden beginnings. It does not promise health, length of days, or protection from harm.
That confession points beyond David to Jesus. The Son of God did not appear as an adult; he was conceived, carried, and born, and he grew through ordinary hidden years in Nazareth. The God who wrote the psalmist's days in his book also ordered the days of Christ's incarnation, ministry, death, and resurrection. The psalm never names the Messiah, and we should not force him into every line. But it prepares the way by insisting that a human life, even an unnoticed one, is God's work. In Christ, God himself took up that kind of life and lived it fully before the Father.
Because Christ is the true human, fully known and fully loved by the Father, those in him share the welcome the psalmist enjoys. Your worth does not rest on what you produce, how visible you are, or how useful you become. It rests on God's work and God's knowledge of you. This passage is not a slogan for or against any technology; it speaks of God's craftsmanship and the psalmist's trust. When you wake, you are still with him. That is the gospel's logic: God's action first, then our grateful response.
What faithful response looks like in ordinary life
Read Psalm 139:13–16 slowly as your own prayer. The psalmist looks back to a stage of life he cannot remember and did not control, and he names God as the one at work there: you formed my inmost being, you knit me together. Nothing about his beginning was hidden from God, and nothing about yours is either. Let that settle the question of your worth before you ask what any tool can do with you. Your value rests on God's work in making you, not on what you produce, how quickly you produce it, or how well a system measures it.
When you take up new tools, artificial intelligence among them, refuse two things. Do not let a tool define a person as data, a bundle of patterns to be sorted and scored, because Psalm 139:14 says of a human life, "I will give thanks to you, for I am fearfully and wonderfully made." And do not let any tool take the place of the God who alone knows the heart. Receive grace as the ground of that obedience: you are already known and accepted in Christ, so you are not working to earn a verdict. This passage does not promise that any technology will be safe or that your plans will succeed.
Obey in the ordinary hidden places. The psalmist marvels that God's thoughts are precious and vast, more numerous than sand, and that when he wakes he is still with God. That is trust with outcomes left in God's hands, including outcomes he has not promised to reveal. So say the honest word, do the quiet work, treat the person in front of you as more than a profile. You will not remember most of the days God has written in his book, and you do not need to. You are known, and you are with him.
Biblical fidelity check
Read slowly, the psalm moves from darkness to the womb. The psalmist says that even darkness cannot hide him from God, then grounds that confidence in God's forming work: "For you formed my inmost being. You knit me together in my mother's womb" (Psalm 139:13). The images are deliberate and skilled, not mass production, and the confession that follows rests on God's works being wonderful rather than on the psalmist's achievement. The risk here is stretching a song of God's intimate knowledge into a verdict on devices. Verses 15 and 16 are also disputed over the beginning of life and foreordained days, and those debates should not be smuggled into a discussion of machines.
Careful evangelical readers agree that God made human life and that persons bear his image, but they differ over how directly this psalm addresses technology. Some hear a strong word against treating people as data or products; others insist the text says nothing about tools. What stays central is that God alone searches the heart, forms the person, and owns the days. The psalm describes God's work and the psalmist's response; it issues no command about devices, and no created tool can take that seat.

Frequently asked questions
Does the Bible say anything about artificial intelligence?
This passage says nothing about artificial intelligence, so it cannot answer that question directly; it speaks instead about God forming a human person in the womb. The psalmist credits God with shaping his inmost being and seeing his unformed body, and he traces every ordained day before any of them existed (Psalm 139:13–16). That describes God's intimate knowledge of a person, not the making of machines. What stays central is that human life is God's deliberate work, which is a different claim from anything Scripture says about tools we build.
Since God formed me in the womb, how should that shape the way I use technology?
Because God formed your inmost being and knit you together, your life is not raw material for devices to shape however they like; technology is a tool you steward, not an identity it assigns. David says God's eyes saw his body and all his days were written before any of them existed (Psalm 139:16), so your attention and time belong to someone who already knows them. Let that steady you: choose devices and habits that serve the person God made, and bring what you see on a screen under his careful gaze rather than letting it quietly define you.
Does being fearfully and wonderfully made mean my worth depends on what I produce?
No. In this passage the psalmist grounds worth in God's forming work, not in output: God made his inmost being and knit him together in the womb (139:13), and his frame was not hidden from God when he was made in secret (139:15). The thanks of 139:14 responds to being made, not to achieving. Even the days written in God's book are ordained by God, not earned by him (139:16). Your value rests on the Maker's care, so it does not rise or fall with what you produce.
